Scott S Posted May 10, 2009 Share Posted May 10, 2009 I a '30 roadster and when I push the horn button I get a very weak sounding noise, not the typical "ahooga." I am wondering whether there is some sort of lubrication or maintenance for the moving parts. It just sounds like it's stuck. It worked fine last year.

MCHinson Posted May 10, 2009 Share Posted May 10, 2009 You need to remove the screw that hold the back cover on the horn. Remove the back cover, then you can clean the commutator by holding a piece of sandpaper against the commutator while the horn motor is revolving. Apply a few drops of light oil on each end of the armature shaft. You need to make sure you have a good electrical connection. You can then adjust the adjustment screw to get the proper tone.

Scott S Posted May 10, 2009 Author Share Posted May 10, 2009 Thanks. I suspected it need something like that but did not want to just start poking around. Link to comment Share on other sites More sharing options...
